AUTOMATIC LINING-GEMENTING MACHINE.

like reference characters on the rawings indicating like parts in theseveral figures.

This invention relates to a machine for applying a sticky substance Suchas cement to sheet material and is herein illustrated as embodied in amachine for apply lng cement to a piece of lining or doubling materlalwhich is afterward to be attached to a part, such forA example as avamp, of a shoe upper.

The lining or doubling, referred to above, is not the true lining of theupper but 1s placed between the true lining and the upper so as to plumpthe leather and give it the feel of a heavier piece. The material ofwhich such lining or doubling is made usually has a nap or furrysurface, and it 1s desirable first that the cement be applied as far aspossible to this nap only and not to the body of the material, andsecond that the cement be applied in a quantity just suilicient toattach the nap to the leather, since any excess will later causeobjectionable stifl'ening to appear. l

To this end one feature of the invention comprises a cement applyingmember having a plurality of cement carrying disks, a presser memberhaving grooves to receive the edges of said disks, and means forrotating said disks whereby a piece of material presented to saidmembers will have applied to one surface thereof, stripes of cement. Theedge of each disk is spaced from the bottom and side of thecorresponding groove in the presser so that at no time is there anyliability of getting cement upon said presser; and at the same time thematerial when fed between said presser and disks is properly materialshall be light so as to apply the cement to the nap only.

Heretofore machines used for applying cement to linings have commonlycomprised a slowly revolving drum, the lower portion of which dips intoa cement receptacle while the upper part extends above a bench or atable. With such a machine the operatory first lays the lining upon thedrum and then strips it olf and places it upon the piece of leather. I

In order to simplify the cementing operation another feature of thepresent invention consists of a rotatory cement applying member, apresser between which and the cement applying member the material to becemented is passed, means for presenting a piece of material to saidmembers and means for returning the cemented piece back into position tobe removed readily by the operator. Any suitable means may be made useof, and in the illustrative machine two endless' belts are provided, onebelt carrying the material to the upper part of the cement applyingdisks and the other receiving the cemented material and 'carrying itback, cemented side up, to the. front of the machine. These and otherfeatures of the invention including certain details of construction, andcombinations of parts, will be described in connection with anillustrative machine and pointed out in the appended claim.

Referring now to the accompanying drawings,-Figure 1 is a side elevationof-a machine in which the present invention is embodied; Fig. 2 is aplan of the machine; Fig. 3 is a front elevation; Fig. 4 is a detailedsection showing more particularly the relation between the cementapplying member and the presser.

The frame of the machine comprises two plates 1, held together by stayrods 3, and Supporting a cement receptacle 5. J ournaled in the plates 1and dipping into the cement is a cement applying member comprising a hub7, to which are fast a plurality of disks 9. The shaft 10 carries apulley 12 around which, and around a pulley 14 on the driving shaft 39,passes a belt 16.

Above the cement applying member is a presser roll 11 formed with aplurality of grooves 18 to receive the edges of the disks 9, said rollbeing made of wood, and having journals loosely mounted in slots 13 inthe plates 1. Near its outer edges this roll ithe rod 27 'shaft of them11 29, a belt 35,

is provided with grooves 15, the bases of which contact with drivingdisks 17 which are fast to the hub 7 so that the presser roll is drivenfrictionally from the cement applying member. The relation between thefriction driving disks 17 and the cement applying disks 9 is such thatthe latter disks extend part way into the grooves 18 of the presserroll, but not to the bottoms of said grooves, and that the taperingridges 19 of the presser roll extend into the spaces between the disks9. The disks and ridges are thus so spaced with respect to each otherthat no cement can reach the presser roll whether or not a piece ofmaterial is bein cemented although the disks 9 carry at al times attheir outer edges a coating of cement. The material to be cemented(indicated at 100 in Figs. 2 and 4) passes between the disks and presserroll during the operation of the machine and is thereby striped on itsunder side with a small amount of cement.

In order to feed the material into position to beemented, and to returnthe cemented material into position to be removed readily from themachine, the following conveying mechanismv is provided. Ad-

justably mounted in two pairs of slots in the plates l, one of each pairof which is shown at 21 and 23 are two rods 25 and 27, 'said rods beingheld in adjusted position by nuts as shown. Around the rod 25 and aroundav felt covered roll 29 rotatably mounted in the plates 1 passes a belt31, said belt being driven in the direction indicated by the arrows bymeans of a pulley 33 fast to the and a pulley 37 .fast to the drivingshaft 39. When a piece of material is placed upon this belt it iscarried up until the forward edge comes in contact with the disks 9whereupon, by reason of the cement upon these disks, the piece ofmaterial sticks to them and is carried between the disks and the presserroll 11. Fast to the driving shaft 39 is a felt covered roll 41, aroundwhich and around passes a second endless belt 443, said belt travelingin the direction indicated by arrows and serving to deliver the cementedmaterial back to the front of the madera machine. In order to remove thecemented piece of material from the disks 9 strippers 45,-which areattached to the rear wall of the cement receptacle 5, extend betweensaid disks.

Power having been applied to the pulley 47, the operation of the machineis as follows: The operator stands at the front of the machine andplaces the pieces of lining one by one upon the belt 31 in the positionindicated in Fig. 2. rlhe piece of material is automatically carriedbetween the disks 9 and the presserroll 11 in the manner indicated inFig. 4, and is presently stripped from the disks by strippers 45; In thefurther advance of the piece, as the free end contacts with thetraveling belt 43, said belt carries said end to the left as viewed inFig. 1, thereby completing the turning over of the piece andsubsequently carrying' the piece, Icemented side up, to the front of themachine where it can readily'be seized by the operator.

Having described my invention, what ll claim as new and desire to secureby Letters Patent of the United States is:-l

A machine for cementing lining material for boots and shoes having, incombination, a cement applying member comprising a hub and a pluralityof thin disks mounted thereon in spaced relation, areceptacle for cementinto which the lower portions of said I disks dip, a bodily movablepresser roll havmg grooves arranged to receive the edges of said disks,a conveyer at the front of the machine having an upwardly 'inclinedoperative run adapted to present the forward edge of the lining materialto the upper portion of said disks, and a second conveyer locatedbeneath said receptacle and arranged to deliver the cemented material toa point just below the lower portion of saidirst named conveyer.

In testimony whereof 1 have signed my name to'this specification in thepresence of two subscribing witnesses.
